Boat wagon

Abstract

A boat wagon adapted to be pushed or moved along an underlying wagon supporting surface includes two legs and a legs interconnecting member. The horizontal distance between the legs can be adjusted. The legs interconnecting member is formed of a number of removable elements adapted to co-act with each other. The span between the legs is adapted for road transport by removing one or more of the removable elements. The legs can be adjusted to adapt to a second span for boat transport by fitting one or more of the removed elements to wagon related and leg associated sub-parts.

What is claimed is:  
     
       1. A U-shaped boat wagon that is adapted to be pushed or moved along an underlying wagon supporting surface, comprising: 
       two legs and a legs interconnecting member configured such that the horizontal distance or span between the legs can be adjusted;  
       wherein the legs interconnecting member is comprised of a number of elements adapted to co-act firmly and easily removably with each other, wherein the span of the legs is adapted for a road transport by removing one or more of the removable elements, the legs can be adjusted to adapt to a second span for a boat transport by fitting one or more of the removed elements to associated first coupling means and second coupling means of the legs interconnecting member, and the wagon further includes steerable wheels and mechanical drive means, which enable the legs to be moved closer together or wider apart with the aid of said steerable wheels.  
     
     
       2. A wagon according to  claim 1 , wherein said legs interconnecting member is comprised of a beam structure. 
     
     
       3. A wagon according to  claim 1 , wherein said first and said second coupling means are comprised of flanges and screw joints. 
     
     
       4. A wagon according to  claim 1 , further including telescopic rods extending parallel with said legs interconnecting member. 
     
     
       5. A wagon according to  claim 1 , wherein said legs interconnecting member is comprised of more than two mutually parallel beam-parts. 
     
     
       6. A wagon according to  claim 1 , further including a support plate that is adapted to support a forward region of a boat carried by the wagon. 
     
     
       7. A wagon according to  claim 1 , wherein the wagon further includes a frame structure and each of the steerable wheels is supported by a piston-cylinder device that is active between said wheels and the frame structure of said wagon. 
     
     
       8. A wagon according to  claim 7 , characterized by including two the piston-cylinder devices which are hydraulically connected in parallel. 
     
     
       9. A wagon according to  claim 8 , wherein a volume of hydraulic fluid in said piston-cylinder devices is enclosed through the medium of valve means so as to allow pendular movement. 
     
     
       10. A U-shaped boat wagon that is adapted to moved along an underlying wagon supporting surface comprising, in combination: 
       two legs;  
       a plurality of wheel sets connected to each leg, each set of wheels comprising a pair of wheels, the wheels of each pair being positioned on opposite sides of a respective leg to support a center of gravity of the respective leg;  
       a legs interconnecting member connecting the two legs together and comprising two mutually parallel hollow beam parts, the beam parts having one or more removable elements such that a span of the legs is adapted for road transport by removing one or more of the removable elements, the legs can be adjusted to adapt to a second span for a boat transport, by fitting one or more of the removed elements to associated sub-parts of the legs interconnecting member; and  
       at least one supportive beam to be inserted into a respective hollow beam part to facilitate removing one or more of the removable elements and fitting one or more of the removed elements to the associated sub parts.  
     
     
       11. The wagon according to  claim 10 , wherein mutually opposite end-parts of the removable elements are provided with first coupling means for co-action with corresponding second coupling means belonging to adjacent elements of the hollow beam parts; and the second corresponding coupling means are also adapted to mutually form corresponding coupling means therebetween. 
     
     
       12. A The wagon according to  claim 11 , wherein the first and second coupling means comprise flanges and screw joints. 
     
     
       13. The wagon according to  claim 10 , further including telescopic rods extending parallel with the legs interconnecting member. 
     
     
       14. The wagon according to  claim 10 , further including a support plate that is adapted to support a forward region of a boat carried by the wagon. 
     
     
       15. The wagon according to  claim 10 , wherein the wagon further includes a frame structure, and one set of wheels comprises a front wheel set, wherein each of the front wheels is supported by a piston-cylinder device that is active between the front wheels and the frame structure of the wagon. 
     
     
       16. The wagon according to  claim 15 , wherein two of the piston-cylinder devices are hydraulically connected in parallel. 
     
     
       17. The wagon according to  claim 16 , wherein a volume of hydraulic fluid in the piston-cylinder devices is enclosed through a medium of valve means so as to allow pendular movement. 
     
     
       18. The wagon according to  claim 10 , further including mechanical drive means and wherein the wheel sets include a set of steerable wheels, the mechanical drive means enabling the legs to be moved closer together or wider apart with the aid of the steerable wheels.
